T all whom it mag concern:

Be it'known that I, RUBY EVA 'PADMAN, a subject of the King of GreatBritain, re-

siding at No. 8 Trevallyn Road, Launceston,

in the State of Tasmania and Common-- wealth ofAustralia, haveinvented anew and useful Improvement 111 Typewrlters, of which the followlnglsaspeclfication. V

- My invention consists essentially in the combination with a typewriterof a 'date stamp so arranged as that, on depressing a ke the rearran eddate on thestam is' first inked and then printed on the letter, invoice,circular or the like which has previously been placed in position inthetypewriter, the date stamp being returned to its normal position on thefinger ofthe operator being lifted from the key.

It is obvious that thezdate stamp may be applied to a typewriter invarious ways, to effect the desired result. I will now describe onemeans by which a date stamp may be combined with a typewriter, so that,on depressing a key, said date stamp is caused to travel forward,without revolving, against a hinged inking pad in front thereof, thustransferring the necessary amount of ink from the pad to the prearrangeddate on the date stamp. The further forward movement of the date stampcauses the hinged inking pad to drop, permitting the date stamp tocomplete its travel and imprint its previously inked date upon theletter, invoice, circular or the like, in position in the typewriter.When this has been efiected, and the finger of the operator has'beenremoved from the said key, a spring returns the date stamp to itsoriginal position, and another spring returns the hinged inking pad toits original position, ready for impressing the same date on the nextletter, invoice, or circular.

The date stamp and its appurtenant parts are contained within a suitablecasing which may be formed integral with the right hand end of the frameof a typewriter, or attached thereto in any approved way. In thedrawings hereto annexed, I have shown the date stamp and its appurtenantparts at- 0 taohed to the right hand end of the frame of an Underwoodtypewriter.

Referring to the drawings hereto annexed Figure 1 is a plan View of thedate stamp 5 and its appurtenant parts within the casing beforevreferred to, bemgremoved.

Figure 2 is a side elevation of Figure 1,

one "of. the sides of the casing being removed. Figure 3 1s as1deelevat1on-of the casing, one of its sides being removed, and showingthe position ofthe date stamp and its appurtenant parts, when theikeyhas been depr'essed tojlprint the necessary date on the letter, invoice,or circular in the typewriter.

Figure 4: isa plan view of portion of an Underwood typewriter, 'ShOWIHgmy inven" tion attached thereto,the date stamp and it's appurtenantparts being in the position they occupy after the date has been printed.

Figure 5 is a planview of portionof the casing, showing the meansforclamping it to the right hand end of the frame of the typewriter. I I 1i Figure 6 is a side elevation of Figure 5. 1 is aidatestamp:consistingoffour rubber-faced rollers, carrying in relief thenecessary figures and letters to constitute a date. 2 is a horizontalnonrotatable spindle, on which these rollers are mounted. 3 are coiledsprings on the said spindle 2, which press the rollers thereon to ether,

the cover of the casing and prevent them revolving after t e dethe datestamp 1, one end of said rod being formed integral with one of thehorizontal bars i and the other to the opposite one, and consequentlyadapted to move to and fro with said bars 4;. 9'is another horizontalrod extending across the casing at the other end thereof and beingformed integral with said casing. 10 is a lazy-tongs lever, one end ofwhich engages with horizontal rod 8 and the other with horizontal rod 9.is a key the inner end of which is a continuation of portion of saidlazy-tongs lever, and which key projects through a slot (not shown) inthat end of the casing 6' at the opposite end to the date stamp 1. 12 isa container for an inking pad 13, said container being hinged at 14 tothe bottom of the front of the casing 6. 15 is a coiled spring fornormally keeping said hinged travel and the typewriter.

inking pad in its closed position. 16 is another coiled spring connectedat one end to the back of the casing, and, at its other end, to thatportion of the lazy-tongs lever adjacent thereto. 19 is the clamp forclamping the casing 6 to the right hand end of the frame of thetypewriter.

A will be clearly understood, on depressing he key 11, the lazy-tongslever 10 is caused to expand against the resistance-of the spring 16,thus causing the date stamp 1 to travel forward, as previouslyexplained, and without revolving against the hinged inking pad 13. Thefurther forward movement of the date stamp overcomes the resistance ofthe spring 15 and causes the hinged inking pad to drop, thereby per-,

mitting the said date stamp to complete its print its previouslyarranged date on the letter, invoice, or circular, in

When this has been effected, spring 16, on the removal of the operatorsfinger from the key 11, returns the said date stamp to its normalposition within the casing 6, and spring 15 returns the said hingedinking pad to its closed position, ready for the next operation.

I claim 1. In a typewriter the combination therewith of a datestamp,means for causing said stamp to travel forward without revolving, firstagainst a hinged inking pad which it causes to fall, and secondly,against a letter, invoice, circular, or the like, in the typewriter, inorder to impress the necessary date thereon, and springs for returningboth said date stamp and hinged inking pad to their normal positions.

2. In a typewriter, a casing built either into or attached to, the righthand end of the frame of the typewriter, a date stamp carried on ahorizontal spindle atone end of said casing, a horizontal bar on eitherside of the casing, and capable of sliding to and fro in guides on theinside of said casing, said bars being each connected at one end to saidhorizontal spindle, and at right angles thereto, a horizontal rod behindand parallel with said date stamp and capable of moving with saidhorizontal bars, a horizontal rod near the other end of the casing andparallel with the previously mentioned horizontal rod, a lazy-tongslever between and connected to said rods, a key, by depressing whichsaid lever is expanded to op erate the said, date stamp, a hinged inkingpad in front of the said date stamp, a hinged cover to said casing, andsprings for returning both said date stamp and hinged inking pad totheir" normal positions, when required.
